Just keep going up to them and shake the remote back and forth and to make things easier at the screen that says campaign enter in with the plus pad left,left,up,left,right,down,right. if you enter it right there should be a flash of white light. Then start playing and you can't die.

When optimus prime has a low bar follow him and there will be time n your screen to get back to the zone so try to catch him a little and he will stop somewhere. so be careful of the time or its game over.

You have to climb up the walls with the m and the number on the side all the way to the top and throw the generators off when you throw one it gives you extra time just make sure you get to the next one fast enough

Ther's a short cut to Sam when the mission starts, don't follow the drones, turn arond and go to the hi-way turn rite, and at the next turn, you turn thereand whene you see the green dot go there, that's Bobie Bolivias hope I helped.

Step 1: first go in the circle road
step 2: then roam in the circle
step 3: roam untill you find a green thing in your map
step 4: then go at the car lot and wait for the cars
step 5: when they come shoot them fast but remember that ,don 't let them reach the green thing

When shockwave has his forcefield on throw many things at the shield
when he turns into robot mode hit him as many times as you can before that when he is in vehicle mode he shoots many buildings he will destroy all the buildings when you are done with him he will transform into a helicopter catch up with him and repeat everything again.

Play the chapter with the character you wont to be. Beat the chapter.
And when its over you will be some other character, and then just die.
(blowing up buldings will bring tanks and MH52 pave low's. They will atk you)

You cant realy hurt humans ion the game. But if you are doing the last mishen in walking gints blow up bildings. if not in that level but in the level with megatron vs prime kill the drons. if you are in neather he wont come out

A2:

When you get to the end you don't have to get him to come out of hiding. He is hiding on top of the tallest building so you got to run behind it where its smooth then start climbing when you reach the top you win.

Shot all the drons going there untell they are all robots, and kill them. the secend time the drons come do the same. it sould work. (when the drons are in robot mode they go after you, and not to the car yard)

A2:

I drive straight to the Bolivia car yard and wait for the Decepticons to come to me-then when they arrive lock on shoot them with the A button- they become robots and then destroy them-- just make sure to shoot all cars first in case they come at you in two's or three's

Well you can't. But I know a way to switch characters ypu just can't keep it forever. What I mean is if you quit you can't have him you'll have to do it all over again . okay this is what you do. go to the level which has the character you want to be. now when you complete it. You have to kill yourself if your not the person you want to be. after you kill yourself you should be the character you want to be. try looking it up on youtube. okay man.
